Gold Process Mineralogy SGS

Process mineralogy is often used to predict the response of a gold ore to the various candidate process. In addition, during the processing of a gold ore, periodic mineralogical analyses of ore feed and mill products are needed to determine the nature of the problem if the gold recovery is lower than expected. Therefore, a routine process mineralogical study of gold ores normally includes some or all of the

The process mineralogy of gold: The classification of ore

The principal gold minerals that affect the processing of gold ores are native gold, electrum, Au-Ag tellurides, aurostibite, maldonite, and auricupride. In addition, submicroscopic (solid solution) gold, principally in arsenopyrite and pyrite, is also important. The main causes of refractory gold ores are submicroscopic gold, the Au-Ag tellurides, and very fine-grained gold (<10 µm) locked
